Hi all, I have the old workstation Dell Precision 690 Workstation 2 x dual core intel xenon 3.0 ghz
4gb ram
Samsung 120 ssd with 64 bit windows 7 Ultimate edtion
750w original PSU

I used to run a Geforce GTX275 which was/is fine, but I need Directx 11 for newer games
So i bought a new GPU: asus gtx750ti-oc-2gd5
but I can´t get the signal out to the screen.,, :-(
I have read almost anything regarding this issue on other computers, tried tricks here and there:
Done so far:

Updated the Bios to latest A08

Did a cmos reset battery out.

Uninstalled old gpu driver in safemode and installed the new drivers for the ASUS GTX 750.

Tried a different 6pin power connector

Tried to gain access through teamviewer/andorid phone but here the screen is also black with the new GPU installed.

Tried to take out all 4 ram blocks, install one at the time.
skipped one harddrive so i only needed power to the motherboard and one SSD drive and the new GPU

Took the new asus GPU down to the store and saw it fired straight up in their system.

I have tried all the outputs two DVI´s and one HDMI no luck on the new gpu.
The fans are running on the card and a green power led is lid on the GPU next to the 6pin connector
The Dell boots up fine to windows but no signal...

What am i missing?
Dell´s 690 PCi e 1.1 x16 slot should be forward compatible with the asus gtx750ti-oc-2gd5 which is a pci e 3.0 card as far as i have read on the net.

I really would like to play Alien Isolation soon thx 🙂

Cheers Dan from Denmark.

the board like dell uses are dell designed boards to dells specs. they don't have to meet standard atx specs. just what dell wants for that use if they want it to be set at what ever watts that's what they will do the ones that get this issue the most are the computers that shipped with out a card in them cause that's how dell set it up so they don't need to stress there cheap oem board with a full 75w pci-e slot cause it was not meant to have a card to start with ..

and if it did come with a card it usely a lowend card the may only need lets say 45w so that's where they set it to and so on ...

this is why we do custom builds and not prebuilts boards we fet from asus msi gigabyte are full atx standard boards designed for...

Hi cowboydude99,
I used the 3dguru to uninstall the old geforce gtx275 drivers in windows safemode, and then installed the new drivers from asus website, then a cmos reset, then tried to boot up on the new asus gpu no luck. Do you have another procedure for me to follow? Cheers and thanks for your answer!

Hi Abmario,
nope no display at all, I could verify that windows had booted since i saw my machine online through teamviewer on my android phone.
Cheers and thanks, Dan

So the system actually boots to Windows, but you can't see anything on your screen...

When using team viewer can you look at the NVIDIA control panel? Take a look at which monitor it is using.

Is it direct connection from monitor to GPU or is there a repeater/receiver/converter in place?

How about changing you cable or use the cable in other pc? or use another display?
Check LED on the board if there is steady LED on next to graphics card.. mostly likely no VGA signal.

Though Intel Xeon dual core doesn't have any graphic processor and you have not installed new gpu driver should not be a problem, you still be able to get a signal from your GPU even without any driver.

Have you re-seat your old graphics card and there was display?

This only works if you think your system is running but no display: you turn ON you system again but this time in darkness, once it is ON put flashlight/torch in front of the display and see if you can find some image and disappear without lights on it... This could mean something wrong with your monitor...

some models of store bought computers [dell.hp,acer,ect..] may come with a ''locked or fixed'' bios and may not allow you to change certain hardware as a video card.. this is done to protect them from undue warranty claims and refunds .this is not done to hurt you but to protect them. you really need to see if that upgrade has been proven to work in your model first before you invest money in it .. there are a lot of these threads here at toms to look at some models will allow upgrades and some dont.. and a lot of guys here say ya ya ya when is really no no no...it would be sad you spent $200 on a card that wount post after you installed it as most find out. then get told its your psu and you spend more and end up right back where you are now, but its up to you good luck..


you got to know the the boards in these computers are not like the ones we use to do custom builds witch are open to upgrading with in the boards compatibly . the bios is custom made for there design and just for the parts they authorize to be used on there computers there only guaranteed to work as is out of the box as you bought it ,..


plenty of threads here at toms on that issue you got to read up on

good luck

And yes its a straight cable from the GPU to my smart samsung TV. Tried both DVI and HDMI no luck

yeah I have tried to reseat the old GPU and it works fine with the same cable and smart TV. So there is nothing wrong with the monitor/TV
the steady light you refer to is that on the motherboard or the GPU ?
On the GPU i have the steady green light LED which I think stands for power ok right?
on my motherboard I have seen a steady amber light.

@ junkeymonkey, Thanks for links and answer! Yeah I might be one of the unlucky ones, but then its very random which cards work.
I have seen guys on here with Dell 690´s and new higher spec cards than mine working.
Hope someone here have experience with the ol´Dell 690 and newer cards??

Thanks Dan.

not to say this is your issue but I explained that in one of the links I gave
the gtx 275 is not powerful and may work fin for what it is on a cut back pci-e slot.......

ya -- the thing is there boards dont have to meet atx standard and they will cut back the pci-e slot power from the 75w most high end card require so if they set the pci-e slot power to lets say 45w and the card you upgrade to needs the full 75w to run it will black screen as most find out on this issue

unless you can find solid proof that the card you want works 100% I don't advise it

also it may power the card to where it will display but when the card gets under load it will fail cause its not getting the correct power from the slot as it needs it

I do hope I'm wrong on this for your deal so i'll leave it as that

good luck

Thanks Junkeymonkey,
well power consumption wise I have actually gone a step down from my old GPU Geforce GTX 275 :

From geforce website:
Maximum Graphics Card Power (W)
219 W
Minimum System Power Requirement (W)
550 W
Supplementary Power Connectors
6-pin x2

my new Asus GPU specs from Asus website:
"up to 150W 1 additional 6 pin PCIe power required
So I do´t think I´m lacking power with my 750 watt PSU

Its probably time to make a new machine custom build, save my Samsung ssd and the new Asus GPU .

too bad I was actually quite happy with the Dell 690 huge gaming brick which I got almost for free..🙂

I guess noone here can prove a Dell 690 running with a likewise Directx 11 GPU with great succes?

Cheers
Dan

this is why we do custom builds and not prebuilts boards we fet from asus msi gigabyte are full atx standard boards designed for aftermarket upgradeable parts compatible for it like vid cards also this is why you go to dell for bios and drivers and not the boards manufacture as we do cause it all under dells control as dell sees fit
